본 발명은 포토 다이오드가 구비된 차량용 공조제어 조작 스위치에 관한 것으로서, 보다 상세하게는 차량 실내를 쾌적하게 하기 위한 공조기의 작동 및 토출방향 등을 제어하기 위한 작동조작 스위치를 광소자에 의한 비접촉식으로 구성함으로서 내구성을 향상시킬 수 있도록 한 포토 다이오드가 구비된 차량용 공조제어 조작 스위치에 관한 것이다. The present invention relates to an air conditioning control switch for a vehicle equipped with a photodiode, and more particularly, an operation control switch for controlling the operation and discharge direction of the air conditioner for making the interior of a vehicle comfortable. The present invention relates to a vehicle air conditioning control switch equipped with a photodiode capable of improving durability.

일반적으로 차량에는 여러 가지 기후나 주행조건에서도 탑승자에게 쾌적한 환경을 만들어 주고, 용이한 시계확보를 위한 윈드쉴드 글래스 면상의 결로 및 서리 등을 제거하여 안전한 운전을 할 수 있도록 하는 공기조화기가 설치되고 있다. 공기조화기는 차 실내로 외부공기를 유입시키거나 내부공기를 순환시켜 차 실내의 공기를 청정상태로 유지시킬 뿐만 아니라, 동절기에는 차 실내의 온도를 높이기 위한 난방 시스템을 작동시키고, 하절기에는 차 실내의 온도를 낮추기 위한 냉방 시스템을 작동시켜 항상 차량 실내를 쾌적한 상태로 유지시키는 작용을 한다. In general, air conditioners are installed in vehicles to create a comfortable environment in various climates and driving conditions, and to remove condensation and frost on the windshield glass surface for easy visibility. . The air conditioner not only keeps the air inside the car clean by inflowing outside air or circulating the inside air, but also activates the heating system to increase the temperature inside the car in winter, and in summer By operating the cooling system to lower the temperature, it keeps the interior of the vehicle comfortable.

위와 같이 차량용 공기조화기에는 차 실내의 온도를 적정하게 유지하기 위해 서 토출되는 공기의 토출방향을 제어하기 위해 차량용 공조제어 조작 스위치가 장착되며, 상기 조작 스위치를 회전시킴에 따라 토출되는 공기의 방향이 제어되어 윈드쉴드 글래스의 면상으로 토출되도록 하여 결로 및 서리를 제거하도록 하거나 운전자의 발쪽이나 위쪽 또는 윈드쉴드 글래스 및 운전자 발쪽 등 다양한 방향으로 토출되도록 함으로써 최적의 차량 실내 환경을 유지하게 된다. As described above, the vehicle air conditioner is equipped with a vehicle air conditioning control switch to control the discharge direction of the discharged air in order to maintain an appropriate temperature inside the vehicle, and the direction of the discharged air as the operation switch is rotated. The control is to be discharged to the surface of the windshield glass to remove condensation and frost or to discharge in various directions, such as the driver's foot or the top or the windshield glass and driver's foot to maintain the optimal vehicle interior environment.

도 1은 종래의 실시예에 따른 차량용 공조제어 조작 스위치의 작동상태를 나타내는 블록도이다.1 is a block diagram showing an operating state of a vehicle air conditioning control switch according to a conventional embodiment.

상기에 도시된 바와 같이 인코더 스위치(encoder switch)(101)가 온(on)이 되면 풀업저항에 인가된 전원에 의하여 컨트롤러(102)에는 로(low)상태의 신호가 입력이 되고 인코더 스위치(101)가 오프(off)가 되면 풀업저항에 인가된 전원에 의하여 컨트롤러(102)에는 하이(high)상태의 신호가 입력이 되어 스위치의 작동상태를 감지하고 있다.As shown above, when the encoder switch 101 is turned on, a low signal is input to the controller 102 by the power applied to the pull-up resistor, and the encoder switch 101 is input. When is turned off, a high state signal is inputted to the controller 102 by the power applied to the pull-up resistor to detect the operation state of the switch.

그러나, 종래의 인코더 스위치와 같은 회전식 스위치의 경우 스위치자체를 이용하여 입력회로를 구성함으로써, 스위치의 가격이 상대적으로 비싸고, 디자인에 따라서 스위치내부에 별도의 접촉식 스위치를 내장하기가 용이하지 않을 뿐만 아니라 시간이 지남에 따라 스위치 접촉면에서 발생하는 아크등으로 인하여 접촉면의 카본이 마모되고 절연피막이 형성되어 전기전도성이 떨어지는 등의 내구성 문제점이 있다.However, in the case of a rotary switch such as a conventional encoder switch, the input circuit is constructed using the switch itself, so that the price of the switch is relatively high, and it is not easy to embed a separate contact switch inside the switch according to the design. However, due to the arc light generated from the switch contact surface over time, there is a durability problem, such as the wear of carbon on the contact surface and the insulating film is formed to reduce the electrical conductivity.

본 발명은 상기와 같은 문제점을 해결하기 위해 창작된 것으로서, 본 발명의 목적은 종래의 인코더 스위치와 같은 회전식 스위치를 비접촉식 스위치방식에 의하도록 하여, 종래의 인코더 스위치보다 상대적으로 가격을 저렴하게 하고, 디자인에 관계없이 스위치내부에 별도의 스위치를 내장하기 용이하도록 하여 디자인 용이도를 높이며, 비접촉식 스위치방식에 의함으로써 기존 방식의 스위치 접촉면 마모 등의 문제점을 해결하여 스위치의 내구성을 향상시키고자 함이다.
The present invention has been made to solve the above problems, and an object of the present invention is to make a rotary switch such as a conventional encoder switch by a non-contact switch method, making it relatively cheaper than the conventional encoder switch, Regardless of the design, it is easy to embed a separate switch inside the switch to increase the ease of design, and by the non-contact switch method, it is intended to improve the durability of the switch by solving problems such as wear of the switch contact surface of the conventional method.
